摘　　要：针对V2V通信的连接性能问题,将衰落引起的信道随机性纳入分析,提出了一种在衰落信道中对V2V连接性能的分析算法,并将物理层和MAC层相结合,分析了不同衰落模型下V2V通信系统性能,包括对包丢失率、吞吐量、平均延时等通信性能指标,并通过仿真验证。仿真结果表明,瑞利信道的连接性能比Nakagami-m信道高,但信号的传输性能Nakagami-m信道全面优于Rayleigh信道。An analysis algorithm in fading channel is proposed for the connection performance problem of V2V communication with the channel randomness caused by fading.By combining the physical layer and MAC layer,the performance of V2V communication system under different fading models was analyzed,including packet loss rate,throughput,average delay and other communication performance indexes.The simulation results show that the connection performance of the Rayleigh channel is higher than that of the Nakagami-m channel,but the signal transmission performance of the Nakagami-m channel is better than that of the Rayleigh channel.
